I worked across the street while they renovated the old Carbide an Carbon building over a decade ago. It was always a beautiful building, but they really refurbished it before re-naming it the Hard Rock Hotel. The process took several years.
Crains reports that the name is being changed again. (There's a great picture at the link of the gold detail they did at the top of the tower)
I hope the new owners don't undo the renovations. It sounds like they might.
